Barcelona metro and commuter lines
FGC operates some of the commuter rail network in Barcelona. Voice announcements and signs on trains and stations of lines operated by FGC are exclusively in the Catalan language, unlike in the lines operated by Transports Metropolitans de Barcelona and Renfe which remain bilingual or trilingual (Catalan, Spanish or "Castellano" and eventually English) in order to serve a large and diverse userbase. All lines are overhead DC electrified at 1.5 kV. There are two distinct (and separate) systems:
The Metro del Vallès and Línia de Balmes are 8 standard-gauge lines that run from Plaça de Catalunya railway station to Av. Tibidabo (L7, brown on the map), Sarrià (L6, purple) and Sant Cugat del Vallès (S5), and then on to Sabadell (S2) or Terrassa (S1). In rush hour some of them only arrive at Universitat Auntònoma (S6) or at Rubí (S7). The eighth line is the L12, a shuttle subway service between Sarrià and Reina Elisenda.
The Metro del Baix Llobregat and Llobregat–Anoia line are metre-gauge lines that run from the Plaça d'Espanya railway station to Molí Nou-Ciutat Cooperativa (in Sant Boi de Llobregat, L8 – pink on the map), Martorell-Enllaç (S8) and then on to Olesa de Montserrat (S4) and Manresa (R5), or Igualada (R6). There is also an unelectrified metre-gauge freight line to the port of Barcelona, which diverges from the main line between Sant Boi and Cornellà. Along the Llobregat valley, FGC runs on the right bank through Sant Boi de Llobregat, Sant Vicenç dels Horts, Pallejà and on to Martorell (Enllaç), whereas the broad gauge line R4 runs on the left bank through towns Sant Joan Despí, Sant Feliu de Llobregat, Molins de Rei and on to Martorell.
The line numbering is as follows:
L-prefixed lines (L for Línia – line) are treated as part of the Barcelona metro system, which consists of L1-L5 for the metro proper, L6-L8 on the FGC, L9 and L10 partially open and partially under construction, and L11, a short light rail line system in the northwest – see Barcelona Metro. L6 and L7 used to be known as U6 and U7 (U for Urbà – urban), while L8 was formerly known as S3.
S-prefixed lines (S for Suburbà) are suburban lines, extending into metropolitan fare zone 2 or 3.
R-prefixed lines (R for Rodalies) are Interurban lines, extending beyond zone 3. Lines R1-R4, R7 and R8 are run by Rodalies de Catalunya (currently operated by Renfe), R5 and R6 are run and operated by FGC.
